The present invention relates to a pharmaceutical formulation comprising 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or a pharmaceutically acceptable alkanesulphonate salt thereof. More specifically, the present invention relates to a pharmaceutical aqueous formulation comprising 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or a pharmaceutically acceptable alkanesulphonate salt thereof, that is a clear solution. Such a formulation is particularly suitable for intravenous or parenteral administration to a patient.

1-(4-{[4-(Dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, and preparations thereof, are disclosed in WO2009/143313. The compound is an inhibitor of PI3 kinase and mTOR that is useful for the treatment of cancer.

A crystalline form of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, and process for the preparation thereof, are disclosed in WO2010/096619.

WO2016/097949 describes a pharmaceutical aqueous solution formulation suitable for intravenous administration comprising (i) 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or a lactate salt thereof, lactic acid and water, wherein 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea is present at a solution concentration of less than 6 mg/ml and sufficient lactic acid is present to provide a clear solution; or (ii) 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or a phosphate salt thereof, orthophosphoric acid and water, wherein 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea is present at a solution concentration of less than 4 mg/ml and sufficient orthophosphoric acid is present to provide a clear solution. Lyophilisation of such formulations are also described. Of the many acids tested (i.e. citric acid, succinic acid, acetic acid, glycine, tartaric acid, maleic acid, malic acid, hydrochloric acid, lactic acid and orthophosphoric acid), only lactic acid and orthophosphoric acid are found to be capable of achieving a clear solution with a concentration of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea of 3 mg/ml or above.

1-(4-{[4-(Dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, also known as gedatolisib, has the chemical structure:

1-(4-{[4-(Dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea may be prepared in crystalline form and is chemically and physically stable at 25° C. and 60% Relative Humidity (RH) for up to 3 years in this form. However, this free base is insufficiently water soluble to allow the preparation of an aqueous solution formulation suitable for intravenous or parenteral administration at the therapeutic dosage levels required.

There is a need to develop a pharmaceutically acceptable aqueous solution formulation of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea that is (a) chemically stable on storage (e.g. at 25° C. and 60% RH), (b) that will facilitate effective intravenous (or parenteral) administration of the drug to a mammal, including a human being, and (c), preferably, to achieve a solution concentration of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea that is at least 6 mg/ml.

A solution concentration of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea that is at least 6 mg/ml is desirable to allow dose administration to subjects using a single vial presentation of the commercial drug product. A lyophilised drug product (for reconstitution) containing less than 6 mg/ml drug product solution will require multiple vials to deliver the required therapeutic dose. A multiple vial approach to dose delivery is not desirable given current regulatory expectations for these product types.

Preferably, the formulation is suitable for intravenous or parenteral administration of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea in view of the particular pharmacokinetic and bioavailability characteristics of this drug.

It is essential that an intravenous formulation of any drug is a solution to facilitate safe and effective administration to a patient. It must be particle-free, and not form a gel or suspension. A clear, aqueous solution is preferred.

A “clear solution” is defined herein as a visually clear solution, which may bear a solution opalescence, that is essentially free from any visible particulates that can be observed on a visual inspection. Generally, if any particulate matter is observed, the formulation is not suitable for intravenous administration and should not be utilised as occlusion of blood vessels may occur. Accordingly, in view of the qualitative nature of the visual test, the term “essentially free from any visible particulates” is usually applied when no visible particulate matter is observed.

Particulate matter may be defined as follows:

-   -   speck—discrete particle whose shape cannot be determined without         magnification     -   smoke or swirl—fine particles that look like smoke or a tornado         and usually originate from the sample vial floor and twist         upward as the vial is swirled     -   flocculent material—loosely aggregated particles or soft flakes     -   particulates with a definite shape or characteristic can be         described as glass-like, metallic-looking, etc.

The visual inspection can be conducted in accordance with the method defined in European Pharmacopoeia Method 2.9.20 entitled “Particulate contamination: visible particles”. This method determines particulate contamination of injections and infusions by extraneous, mobile, undissolved particles, other than gas bubbles, that may be present in the solutions. The test is intended to provide a simple procedure for the visual assessment of the quality of parenteral solutions as regards visible particles.

In European Pharmacopoeia Method 2.9.20 the apparatus (see “FIG. 2.9.20.-i” shown in FIG. 3) consists of a viewing station comprising:

-   -   a matt black panel of appropriate size held in a vertical         position     -   a non-glare white panel of appropriate size held in a vertical         position next to the black panel     -   an adjustable lampholder fitted with a suitable, shaded,         white-light source and with a suitable light diffuser (a viewing         illuminator containing two 13 Watt fluorescent tubes, each 525         mm in length, is suitable). The intensity of illumination at the         viewing point is maintained between 2000 lux and 3750 lux,         although higher values are preferable for coloured glass and         plastic containers.

The Method states: “Remove any adherent labels from the container and wash and dry the outside. Gently swirl or invert the container, ensuring that air bubbles are not introduced, and observe for about 5 seconds in front of the white panel. Repeat the procedure in front of the black panel. Record the presence of any particles.” A suitable method in accordance with European Pharmacopoeia Method 2.9.20 that has been used for the present invention is described in Example 1(i).

Other validated methods may be also be used for the dermination of if any visible particulates are present. Such methods include Optical Polarised Microscopy (“OPM”). A suitable OPM method that has been used for the present invention is described in Example 1(ii).

The present invention relates to a pharmaceutical aqueous formulation comprising 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or a methanesulphonate or ethanesulphonate salt thereof, methanesulphonic acid or ethanesulphonic acid, and, optionally, a pharmaceutically acceptable beta- or gamma-cyclodextrin, that is a clear solution (hereafter “the formulation of the invention”).

Preferably, methanesulphonic acid (and methanesulphonate salts) are used in the formulations of the invention.

In an embodiment of the invention is provided a pharmaceutical aqueous solution formulation comprising (a) 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or a methanesulphonate salt thereof, methanesulphonic acid and water, wherein 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea is present at a solution concentration of less than 35 mg/ml or up to 30 mg/ml and sufficient methanesulphonic acid is present to provide a clear solution; or (b) 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or an ethanesulphonate salt thereof, ethanesulphonic acid and water, wherein 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea is present at a solution concentration of less than 35 mg/ml or up to 30 mg/ml and sufficient ethanesulphonic acid is present to provide a clear solution.

In an embodiment of the invention is provided a pharmaceutical aqueous solution formulation comprising (a) 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or a methanesulphonate salt thereof, methanesulphonic acid and water, wherein 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea is present at a solution concentration of from 6 to 30 mg/ml and sufficient methanesulphonic acid is present to provide a clear solution; or (b) 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea, or an ethanesulphonate salt thereof, ethanesulphonic acid and water, wherein 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea is present at a solution concentration of from 6 to 30 mg/ml and sufficient ethanesulphonic acid is present to provide a clear solution.

The “solution concentration” values referred to herein relate to the concentration of the free base of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea in the formulation of the invention.

It has been found that the use of methanesulphonic acid and ethanesulphonic acid enables a solution concentration of up to 30 mg/ml of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea to be achieved for a pharmaceutical aqueous solution formulation that is suitable for intravenous or parenteral administration to a patient, i.e. a clear, essentially particle-free solution. Such formulations may have an opalescent hue but they are still essentially particle-free.

Without being bound by theory, the opalescent hue may be caused by chromonic liquid crystal formation. Chromonic liquid crystals are formed by the formation of pi-pi stacked aromatic sections of a molecule forming column like stacks of dimers, trimers and low molecular weight oligomers of the molecules. The stacks that form can be shown via OPM to be non-crystalline microstructures associated to a chromonic liquid crystal. The non-crystalline microstructures exhibit interactions that are not permanent and there is movement to maintain the system in a free energy equilibrium. The opalescence of the solution comes from the alteration of the refractive index of the solution due to the formation of these stacks. OPM micrographs of the solutions will show that there is no crystalline material present and instead there is a chromonic liquid crystal phase. The presence of a liquid crystal phase results in a solution with opacity and/or opalescence due to a difference in refractive index within the solution formed. For a discussion on liquid crystal formation see “Optical Properties of Condensed Matter and Applications”, Jai Singh (Editor), ISBN: 978-0-470-02193-4, Wiley, October 2006.

Such a formulation can be directly administered to the patient (in order to avoid degradation occurring), intravenously or parenterally, preferably with the addition of a tonicity modifier. Alternatively, for administration to a patient at a later date, such a formulation, optionally containing a bulking agent and/or tonicity modifier, may be first freeze-dried to prepare a lyophilised solid composition that is chemically stable on storage for preferably at least 2 years, and which lyophilised solid composition then can be constituted, or reconstituted, to provide a clear aqueous solution, preferably with the addition of a tonicity modifier, as necessary, immediately prior to administration to a patient by the intravenous (or parenteral) route. The reconstituted or constituted solution may be added to an infusion bag prior to administration to a patient.

In respect of the formulations comprising methanesulphonic acid, it has been found that above a solution concentration of 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea of 35 mg/ml or above, the necessary clear solutions at the pH required for intravenous administration to a patient are not obtained, or are not obtained consistently.

The preferred concentration of methanesulphonic acid or ethanesulphonic acid for use in a formulation of the invention is from 10 to 200 mM, 20 to 200 mM, 30 to 200 mM or from 50 to 200 mM, and preferably is about 50 mM, about 100 mM or about 150 mM. Preferably, the concentration of methanesulphonic acid or ethanesulphonic acid is about 100 mM. Preferably, about a 100 mM concentration of methanesulphonic acid is used.

The preferred amount of pharmaceutically acceptable beta- or gamma-cyclodextrin for use in a formulation of the invention is from 2 to 30% w/v, 3 to 20% w/v, from 5 to 20% w/v or from 15 to 30% w/v, and preferably is about 20% w/v or 25% w/v. Preferably, the amount of pharmaceutically acceptable beta- or gamma-cyclodextrin for use in a formulation of the invention is about 20% w/v.

If the formulation of the invention is to be freeze-dried to provide a lyophilised solid composition, a bulking agent may be added to the formulation prior to the freeze-drying process commencing. A bulking agent may not be present if the formulation of the invention contains a pharmaceutically acceptable beta- or gamma-cyclodextrin. The primary function of the bulking agent is to provide the freeze-dried solid with a non-collapsible, structural integrity that will allow rapid reconstitution on constitution of the aqueous formulation prior to administration, and it should also facilitate efficient lyophilisation. Bulking agents are typically used when the total mass of solutes in the formulation is less than 2 g/100 ml. Bulking agents may also be added to achieve isotonicity with blood. The bulking agent may be selected from a saccharide, sugar alcohol, amino acid or polymer, or be a mixture of two or more of any thereof. Preferably, the bulking agent is a sugar or sugar alcohol, or a mixture thereof. Preferably, the sugar is sucrose. Preferably, the sugar alcohol is mannitol.

Preferably, from 5 to 10% w/v of a bulking agent is used, if present.

Reconstitution of the lyophilised solid composition may be achieved by addition of the requisite quantity of water that was present prior to lyophilisation in order that a clear solution is obtained. A tonicity modifier may then be added prior to use.

Constitution of the lyophilised solid composition may be achieved using an appropriate quantity of water and/or an aqueous solution of a suitable tonicity modifier in order to ensure that a clear solution is obtained.

A tonicity modifier may be present prior to intravenous or parenteral administration of the formulation to a patient by injection to avoid crenation or hemolysis of red blood cells, and to mitigate or avoid pain and discomfort to the patient. This requires that the formulation to be administered to the patient has an effective osmotic pressure that is approximately the same as that of the blood of the patient.

Suitable tonicity modifiers are non-ionic tonicity modifiers such as glycerol, sorbitol, mannitol, sucrose, propylene glycol or dextrose, or a mixture of any 2 or more thereof. Preferably the non-ionic tonicity modifier is dextrose, sucrose or mannitol, or is a mixture of any 2 or more thereof.

Preferably, from 1 to 5% w/v of a tonicity modifier is used.

Aqueous pharmaceutical formulations of the invention that are suitable for intravenous administration generally have a pH of from 3 to 9. However, lower pH values are tolerated in certain settings. Preferably, the pH is from 3 to 8 or from 4 to 8.

The formulation of the invention may be used for the curative, palliative or prophylactic treatment of cancer in a mammal, including a human being. The cancer to be treated may be selected from the group consisting of leukemia, skin cancer, bladder cancer, breast cancer, uterus cancer, ovary cancer, prostate cancer, lung cancer, colon cancer, pancreas cancer, renal cancer, gastric cancer and brain cancer.

ANALYSIS OF EXAMPLES 1-18

The Examples shown in the following Table were analysed by the visual method defined in European Pharmacopoeia Method 2.9.20 and the OPM method both as described in Example 1. The results are tabulated below.

Further, the formulations of Examples 1, 2 and 6-18 were each lyophilised by the same method used in Examples 3(b) and 4(b) and then each reconstituted by the same method as used in Examples 5A and 5B.

In this Table “particle-free” means that the the formulation was visually clear and free of visible crystallites or particulates, and “opalescent, particle-free” means that the the formulation was free of visible crystallites or particulates but had a solution opalescence that is thought to result from the formation of a chromonic liquid crystal phase. There are Examples shown where the opalescence disappears on reconstitution of the formulation following lyophilisation. All Examples studied are free of visible crystallite or particulate matter and meet the required “clear solution” definition as described earlier.

Inject the check standard preparation according to the chromatographic conditions above. The response factor (calculated from the area, standard weight, dilution factor and purity factor of the standard) of this check standard preparation must be within ±2% of the standard preparation.

After the system suitability has been demonstrated, inject the blank solution, standard preparation and prepared test samples, followed by an injection of the standard preparation, according to the chromatographic conditions above. It is recommended that no more than 6 test samples be injected between standard preparation injections. For each injection (standard and sample), measure the retention time and area of the 1-(4-{[4-(dimethylamino) piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea peak in each chromatogram. For each sample injection, also measure the retention times and peak area of any peaks present in the sample injection that do not appear in the blank injection. Do not integrate gradient artifacts, if present. Compare the blank injection chromatogram to the sample chromatogram to determine which peaks in the sample are related to the blank and gradient artifact peaks. Calculate the % w/w degradants and report the individual degradant peaks which are at or above 0.05% w/w. Unknown degradants should be reported individually by their relative retention time. Known degradants should be reported individually by name.

The results are summarised in the Tables below.
